⭐ Greek Yogurt (Best Gluten-Free Option)
1:1 (1/4 cup Greek yogurt per 1/4 cup sour cream)Greek yogurt works well because it has a comparable fat content and acidity level to sour cream, which helps tenderize the gluten and contributes to the flakiness of the pie crust. The protein content also supports dough structure without making it tough.
For best results, use full-fat Greek yogurt and avoid varieties with added flavors or sweeteners. If the yogurt is too thick, you can thin it slightly with a teaspoon of milk to match sour cream’s consistency.
The final crust will be nearly indistinguishable from one made with sour cream, with a slight tang and tender crumb, making it an excellent direct substitute.
